RTV112 - DC Products

1 Technical Data Sheet RTV112 . Description RTV102, RTV103, rtv106 , RTV108, RTV109, RTV112 , RTV116 and RTV118 one-component, ready-to-use adhesive sealants are extremely versatile. They cure to a tough, durable, resilient silicone rubber on exposure to atmospheric moisture at room temperature. Acetic acid vapors are released from the sealant surface as a by-product of cure. RTV102, RTV103, RTV108 and RTV109 sealants are standard strength paste consistency Products which can be applied to vertical and overhead surfaces where pourable/self-leveling sealants are not practical. RTV112 and RTV118 sealants are self-leveling Products which are preferable to paste-consistency sealants when flow into small crevices and hard-to- reach places is desired.

2 rtv106 sealant is paste-consistency sealant. RTV116 sealant is a self-leveling sealant. Both rtv106 and RTV116 sealants are standard strength high- temperature sealants. Since all these sealants utilize a moisture cure system, they must not be used in thicknesses of greater than 6mm (1/4 in.). Where section depths exceed 6mm (1/4 in.), Momentive Performance Materials one component, addition cure or two-component silicone rubber compounds are recommended.

8 Product Safety, Handling and Storage Customers should review the latest Material Safety Data Sheet (MSDS) and label for product safety information, safe handling instructions, personal protective equipment if necessary, and any special storage conditions required for safety. MSDS are available at or, upon request, from any Momentive Performance Materials (MPM) representative. For product storage and handling procedures to maintain the product quality within our stated specifications, please review Certificates of Analysis, which are available in the Order Center. Use of other materials in conjunction with MPM Products (for example, primers) may require additional precautions.

9 Please review and follow the safety information provided by the manufacturer of such other materials. Processing Recommendations Surface Preparation RTV102, RTV103, rtv106 , RTV108, RTV109, RTV112 , RTV116 and RTV118 sealants will bond to many clean surfaces without the aid of primers. These surfaces typically include many metals, glass, ceramic, silicone rubber and some rigid plastics. These adhesive sealant Products will also produce fair bonds to organic rubber and to some flexible plastics not containing fugitive plasticizers (which migrate to the surface, impairing adhesion). An evaluation should be made to determine bond strength for each specific application. For difficult-to-bond substrates, use of a primer is suggested.

10 Primers SS4004, SS4044 and SS4179 are recommended for use with these sealants. Complete information and usage instructions for these primer Products are contained in a separate product data sheet. Where adhesion is required, surfaces should be thoroughly cleaned with a suitable solvent such as naphtha or methyl ethyl ketone (MEK) to remove dirt, oil and grease. The surface should be wiped dry before applying the adhesive sealant. When solvents are used, proper safety precautions must be observed. Application and Cure Time Cycle Paste-consistency Products may be applied directly to clean or primed substrates. Where broad surfaces are to be mated, the sealant should be applied in a thin, less than 6mm (1/4 in.)
